Definitions

  • the invention relates to a method for manufacturing products from an at least thermoplastically deformable material. Such a method is known, for instance, as injection molding.
  • the material to be formed such as plastic is heated in a plasticizing device to a temperature such that the material becomes virtually liquid, at least plastic and low-viscous, whereupon the material is introduced under high pressure into a mold cavity of an injection molding mold.
  • the material is distributed such that the mold cavity is completely filled, whereupon the material is allowed to cure by cooling down.
  • the product is taken out by opening the mold and ejecting the product.
  • a further disadvantage of this apparatus is that when materials are used with a low viscosity and/or with shallow mold halves, the material flows from the mold cavity before the mold halves are moved together, so that the earlier mentioned problems occur to an even larger extent.
  • US 4522778 discloses a method and apparatus for the production of parts made from plastic material using an injection press in which the mold cavity is defined by a mold surface and the surface of a moveable piston. Firstly, the material is introduced into the mold cavity and during injection the piston is kept stationary for a time to form a rough mold and then retracted to form a parison. Secondly, after injection has been completed the piston is advanced again, and maintained in position while cooling takes place. Thirdly, the mold is opened and the part rejected.
  • EP 0999029 discloses a molding machine for molding microparts, which includes a plasticizing portion operatively connected to an injection portion and a mold portion.
  • a linear member is associated with the injection portion to permit molding times of 0. 01 seconds at pressures up to about 690 MPa during injection of the molten plastics material into the mold portion.
  • the shape of the mold cavity complies with the micro part to be manufactured.
  • plastics in particular also plastics with a high melt, i.e. plastics with a low viscosity in plastic state.
  • An object of the invention is to provide a method with which, in a relatively rapid and simple manner, products can be manufactured, with relatively simple means, which products, moreover, can have relatively large, thin-walled surfaces, in particular products with wall thicknesses which are relatively small and flow path which are relatively long, smaller or longer, respectively, than matching the melt flow index associated with the material from which the product is manufactured.
  • the disclosure further contemplates providing an improved use of an injection mold with a slide.
  • the invention relates to a method for forming products, characterized by the features of claim 1.
  • plastic is introduced into the mold cavity while the or each slide is retracted therefrom at least partly or is pushed back upon injection, so that additional flow space is obtained.
  • the resistance the plastic experiences is reduced, so that the injection pressure can be kept low, for instance largely below the standard injection pressure for conventional injection molding of a similar type of product from the same plastic.
  • standard pressures can be read from standard tables and, as a rule, are dependent on the plastic and the manner of injection, the projected surface of the products to be formed jointly and the wall thicknesses.
  • the closing pressure can also be kept low in relation to conventional injection molding, readable from the same or comparable tables on the basis of substantially the same quantities. This is directly clear to the skilled person.
  • the or each slide is moved rapidly into the mold cavity, such that the eventual product shape is obtained.
  • the speed of the or each slide is then set such that adiabatic heat development occurs in the plastic, so that the temperature is increased again to approximately the melting temperature of the plastic.
  • partially solidified material will become liquid again and be pushed further into the mold cavity, while, furthermore, the remaining flow paths are relatively short so that relatively thin product parts can be formed.
  • the rate of movement of the or each slide is preferably high, such that the complete movement of the slides is carried out in a fraction of the cycle time of a product cycle, for instance in less than 10%, more in particular in less than 3% of the cycle time, preferably less than some tenths or hundredths of seconds, more in particular microseconds.
  • this rate is set such that the desired temperature increase occurs, while the plastic properties are prevented from being adversely thermally influenced.
  • the distance between the end of the or each slide, leading in the direction of movement and facing the mold cavity in the retracted position, at least partly moved from the mold cavity, and an oppositely located wall part of the mold cavity or slide is set depending on at least the melt of the plastic, i.e. the viscosity of the plastic upon injection.
  • the distance is to be slightly greater than with a lower melt.
  • a thermoplastic material such as a plastic, in particular a thermoplastic plastic
  • a thermoplastic material can be introduced into a mold cavity while the mold as such is closed and the or each slide is in, or is being brought into, a retracted position at introduction of the material, so that the volume of the mold cavity is relatively large with respect to the volume of the product to be eventually formed.
  • the or each slide can be moved forcefully and, in particular, with speed into the mold cavity, at least into the material introduced therein, so that this is pushed away. With it, a speed is developed such that, as a result of the movement of the or each slide, heat development occurs in the material.
  • the movement means are designed such that the slide can move at the desired high speed and with the desired accuracy.
  • the movement means and the slide are designed such that adiabatic heat development occurs, so that the temperature in the material rises preferably above the melting temperature of the respective material.
  • the closing means are included at least partly in or on the mold, preferably such that no press is required or that a press without guide rod can suffice.
  • blocking means can be provided on the mold for holding the mold in closed condition during introduction of the material and displacement of the or each slide.
  • the mold With the apparatus, the mold can be held closed with relatively little closing pressure and the plastic can be introduced, in comparison with a conventional injection molding apparatus.
  • feed pressures of between, for instance, 350 bars and 1000 bars or more are used, with closing pressures of, for instance, 0.25 to 1.25 ton/cm 2 , depending on, in particular, the material used, the wall thickness and the maximum flow path.
  • closing pressures of, for instance, 0.25 to 1.25 ton/cm 2 , depending on, in particular, the material used, the wall thickness and the maximum flow path.
  • a feed pressure of, for instance, between 0 and 200 bars excess pressure can suffice, while relatively low pressures are preferred, for instance of some tens of bars or less.
  • an operating pressure of approximately 300 bar (operating pressure of the cylinders of the slides) is given, while the closing pressure can be, for instance, less than 0.2 ton/cm 2 .
  • a closing pressure of 0.025 to 0.1 ton/cm 2 instead of between 0.25 to 1.25 ton/cm 2 can suffice.
  • the advantage appears to be achieved that due to the high speed of the or each slide, as a result of friction, so much heat is introduced into the material that solidification of the material, in particular against the mold parts and in the flow front thereof, is undone so that the viscosity of the material is reduced again, while the remaining length of the flow paths for this flow front at the start of the movement of the or each slide has been considerably reduced relative to the original length thereof.
  • the material can be distributed in the entire mold cavity with less pressure. As the mold is then closed, in a simple manner, the material is prevented from flowing away prematurely.
  • a feed rate can be used of between 100 and 2000 mm/s, more in particular of between 500 and 1000 mm/s. This rate is selected depending on the solidification rate of the plastic used, while it holds that the more quickly the plastic solidifies, the higher the feed rate is chosen to be. Moreover, the rate is selected depending on the mold geometry and, in particular, the de-aeration, such that undesired pressure increase in the mold cavity by compression of air is prevented.
  • wedge-shaped elements are used which, viewed from the mold cavity, are moved behind the or a slide, such that the respective slide is moved as a result of the wedge-shape.
  • at least two wedge-shaped elements are used which are pushed in opposite directions behind the slide so that a symmetrical load is obtained.
  • At least one slide is provided at the location where the smallest wall thickness is provided in a. product and/or at the location where the flow paths have the greatest length and/or at the location where the flow paths have the greatest complexity.
  • Slides in the mold can have a frontal surface which is relatively large in relation to the projected surface of the product.
  • projected surface is understood to include the surface of the product projected on a plane at right angles to the closing direction of the mold.
  • the frontal surface of the slide can be more than 20% of this projected surface.
  • Surfaces of more than 50%, for instance of 75%, 85% or 95% or more are possible.
  • Fig. 1 shows, in cross-sectional side view, an apparatus 1 to be used with the method according to the invention, provided with a mold 2 with a mold cavity 3 therein.
  • the mold comprises a first, moveable part 4 and a second, complementary part 5, fixedly arranged.
  • the moveable part 4 is guided by suitable guides, which are not shown but can, for instance, be sliding pins, rails, guide rods or a press or the like and which are directly clear to the skilled person.
  • the moveable part is moveable with the aid of devices suitable to that end, represented in Figs. 1-3 as piston-cylinder assemblies 7. It is clear that this may be any suitable device, for instance also a simple press, screw means such as spindles as shown in Fig. 4 , link systems or the like. These can be of relatively light design as they are only meant for moving the part 5, virtually not for absorbing tensile or pressure forces in the further cycle.
  • a slide 8 is provided, moveable in the direction S between a retracted position shown in Figs. 1 and 2 , and an extended position shown in Fig. 3 .
  • two wedges 9 are provided, to be called wedge-shaped elements, which are moveable in a direction P with the aid of piston-cylinder assemblies 10 which are, for instance, hydraulically driven from a central control unit 11.
  • the wedges 9 move in the direction P approximately at right angles to the direction S.
  • the slide 8 is provided with two surfaces 12 inclining in opposite directions, complementary to the top surfaces of the wedges 9, such that if the wedges 9 are moved inwards, towards each other, the slide 8 is moved upwards (directions viewed in the plane of the drawing) towards the extended position and vice versa.

  • an injection device 15 for instance a plasticizing device and, optionally, a pressing device.
  • flanges 16 are provided which, with the aid of blocking means 17, can be pressed and held onto each other, for keeping the mold closed.
  • the blocking means comprise brackets 18 which are moveable with the aid of piston-cylinder assemblies 19 and can be pushed over the flanges 16. In this way, simply, the desired closing pressure can be obtained and maintained.
  • two ribs 21 are provided extending over the entire width of the slide 8, at right angles to the plane of drawing.
  • the distance D between the end 22 of the ribs leading in the direction of movement, and the oppositely located surface 23 of the mold cavity is set with the slide 8 retracted, depending on the desired product wall thickness and the plastic to be used, while the distance is set to be larger according as the melt of the plastic is higher and/or the melting temperature of the plastic is lower.
  • a product can be formed, for instance a sheet with two hinges from thermoplast such as polypropylene or polyethylene, as follows.
  • the mold 2 is closed from the position shown in Fig. 1 , as shown in Fig. 2 .
  • the distance D is then set at a suitable value, such that the space in the mold cavity 3 is relatively great.
  • plastic is introduced into the mold cavity, for instance at a pressure of between 1 and 10 bars excess pressure.
  • the filling pressure is selected such that a desired, short feed time is achieved without the material properties of the plastic being adversely affected and without undesirably high pressure occurring in the mold cavity.
  • the slide 8 is moved forward, in the direction of the extended position, as shown in Fig. 3 , by moving the wedges 9.
  • the speed is selected dependent on the desired adiabatic heat development which should be such that the temperature of the plastic is at least substantially brought back to approximately the melting temperature thereof.
  • Plastic that is, possibly, slightly solidified becomes liquid again and can be forced further into the mold so that a complete filling of the mold cavity is obtained while the product can have wall thicknesses which are, in fact, too small for the melt flow index of the respective plastic/product combination.
  • some hold pressure can still be given with the aid of the injection device 15, so that undesired stresses can be pressed from the product.
  • the mold can be opened again and the product can be taken out.
  • the rate of movement of the or each slide is high such that the time of movement of the slide between the retracted and the extended position is relatively short with regard to the cycle time for the manufacture of a product, for instance between 0 and 10% of that time, also depending on the desired adiabatic healing.
  • This can be determined by way of an experiment for each plastic-product combination or be calculated with the aid of standard tables regarding plastics, the product properties such as dimensions and flow paths, the friction which will occur when moving the slide and the heat capacity and melt temperature of the plastic.
